Cup Grinding Wheel


Grinding cup wheel is a variant of the grinding wheel that is used for the proper finishing of an end product. This is one of the ideal tools that is used in case of aggressive beveling of the glass. The tool functions better than the grinding wheel and outperforms the alkoxide and silicon carbide composition in the grinding wheels.

A cup grinding wheel is fitted into an angle grinder and results in faster and effective grinding. It is generally available in coarse and medium grit sizes and shapes and is used more in the case for glass. .

Our cup wheels for grinding are popular in India and Abroad for Finest Job. Get in touch with our sales team to discuss your requirements and to know more about our grinding wheels, & other abrasives products. Cup wheels are used in tool and cutter grinders where having an additional radial grinding surface is beneficial. A very shallow cup style grinding in slots and crevices is used primarily in cutter grinding and jig grinding .Critical parameters required are fast cut rate, smooth vibration free running and better life.

They operate with their faces generally then are used for surface grinding & tool sharpening, e.g grinding of paper cutter, circular tools, milling cutters etc

Cup Grinding Wheel’s Structure

Cup Grinding Wheels are named Cup Wheels, as the appearance is like a cup and there are two kinds of the same. One is straight and the other is tapper kind Cup Wheels. These cups have a rear wall and round sidewall. Cup type grinding wheel’s walls mainly the sidewall is utilized to crush the job. Although, both the surfaces are of particular thickness but it can be performed on special demands and terms of the customers.
Thicker walls are usually for more element removal, while thinner walls are applied for precise grinding. Industries like automotive sheet spring construction, blades production use the cup wheels, apart from many other construction sectors which need extra radial grinding surface.
Grinding cup wheels work with their features in common for surface grinding & sharpening of devices like a paper cutter, circular tools, etc. One more cutting without a round shape comes by the name of the segment.

Manufacturing Methods of the Cup Grinding Wheel

The grinding cup wheel manufacturing follows two steps:

Hot Pressing

In the hot pressing process, the diamond segments sinter in molds. Then under certain pressure into the press machine. These are fixed into the diamond segments onto the grinding wheels using
1-high-frequency welding,
2-laser welding
3-and mechanical mosaic method

Cold Pressing Method

In the cold pressing method, you first have to press the working layer. Next, go ahead to press the transitive layer of the diamond segments onto the grinding wheel body. Then connect the segments with the help of the wheel’s body teeth. These segments are then sintered onto the furnaces so that they can be sintered without a press.
The cup-shaped grinding wheels (installed on the concrete grinders) are useful to grind the abrasive building materials such as
Marble Etc.

There are certain specifications need to follow in case of grinding cup wheel such as :
1-Never initiating grinding in the outside of a cup wheel
2-If a cup type grinding wheel looks bumped or damaged then it should be discarded.
3-Working with the grinding wheels
